摘要
A simplified method of designing fully stressed piles and beams with optimum length in a Winkler's medium,end-loaded by an orthogonal force and without any point constraint,is proposed. A numerical algorithm distributing the mass by means of the Fully Stressed Design ( FSD) method and updating the moment by finite elements has been first implemented. The use of the FSD method is in general quite simple,and allows to obtain optimum,or close to the optimum,solutions. After having distributed the mass through the FSD method,the length has been finally optimised by means of a heuristic procedure.
